Intel Arc G3 Extreme vs NVIDIA GeForce RTX 4070 SUPER Comparison

Intel Arc G3 Extreme and NVIDIA GeForce RTX 4070 SUPER represent two fundamentally different approaches to graphics processing, one an integrated solution built for mobility and efficiency, the other a dedicated add-in board designed for maximum desktop throughput. The database contains no overlapping benchmark scores for these two parts, so the comparison rests entirely on architectural specifications, recorded performance metrics for the RTX 4070 SUPER, and the physical constraints of each design.

Where Each One Wins

The Intel Arc G3 Extreme wins in scenarios where power draw and physical footprint are the primary constraints. Its 80 W TDP and IGP bus interface mean it requires no power connectors and occupies no expansion slot, making it suitable for compact, portable devices where a discrete GPU cannot physically fit. The Arc G3 Extreme also holds an advantage in raw clock speed, with a 2500 MHz boost clock compared to the RTX 4070 SUPER’s 2475 MHz boost, though this advantage is largely irrelevant given the massive difference in shading units.

The NVIDIA GeForce RTX 4070 SUPER wins in every computational category that matters for gaming and professional rendering. Its 7168 shading units dwarf the Arc G3 Extreme’s 1536, a 4.7x advantage. The RTX 4070 SUPER delivers 35.48 TFLOPS of FP32 performance versus 7.680 TFLOPS for the Intel part, a 4.6x gap. Texture fill rate favors NVIDIA at 554.4 GTexel/s versus 120.0 GTexel/s, and pixel rate favors NVIDIA at 198.0 GPixel/s versus 60.00 GPixel/s. The RTX 4070 SUPER also has 56 RT cores versus 12, and 224 tensor cores versus none listed for Intel.

Memory is another decisive win for the discrete card. The RTX 4070 SUPER has 12 GB of dedicated GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth. The Arc G3 Extreme relies on System Shared memory, meaning its bandwidth is System Dependent and its capacity is whatever the host system allocates. For memory-intensive workloads such as high-resolution textures or large datasets, the discrete GPU’s dedicated bandwidth is the clear advantage.

Architecture Differences

The two GPUs come from different process nodes and foundries. Intel fabricates the Arc G3 Extreme on a 3 nm node at Intel’s own foundry, while NVIDIA uses a 5 nm node at TSMC. The Intel chip, codenamed Panther Lake, uses the Xe3-LPG architecture from the Arc Graphics-M generation. NVIDIA’s AD104 chip uses the Ada Lovelace architecture from the GeForce 40-series.

Transistor counts and die sizes are only recorded for the NVIDIA part. The AD104 contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². Intel’s transistor count and die size are listed as unknown in the database, so no direct comparison is possible on those metrics.

The RTX 4070 SUPER’s memory subsystem is fully specified: 12 GB of GDDR6X at 1313 MHz with 21 Gbps effective speed, on a 192-bit bus, delivering 504.2 GB/s. The Arc G3 Extreme’s memory is entirely System Shared, with the type, bus width, and size all marked as System Shared, and bandwidth marked as System Dependent. This means the Intel part’s memory performance varies with the host platform, while the NVIDIA card’s is fixed and known.

The RTX 4070 SUPER includes 224 tensor cores, which the Arc G3 Extreme does not have listed. The Intel part’s FP16 throughput is 15.36 TFLOPS at a 2:1 ratio, while the RTX 4070 SUPER achieves 35.48 TFLOPS at a 1:1 ratio, indicating full-rate FP16 on the NVIDIA architecture.

API support is identical for both: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4070 SUPER uses a PCIe 4.0 x16 bus interface, while the Arc G3 Extreme is an IGP with no bus interface beyond the integrated connection. Display outputs on the NVIDIA card are 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Intel part’s outputs are Portable Device Dependent.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results between these two GPUs, and the Intel Arc G3 Extreme has no standalone benchmark scores listed. The RTX 4070 SUPER does have a full set of recorded benchmarks. Its average benchmark score is 43223, placing it in the 83rd percentile of all GPUs. The closest rivals in the database, by average score, are the NVIDIA Quadro M6000 24 GB at 43262 with a delta of -0.1%, the NVIDIA GeForce RTX 5050 Mobile at 43268 with a delta of -0.1%, and the NVIDIA Quadro M6000 at 43301 with a delta of -0.2%. The RTX 4090 Mobile sits at 43667 with a delta of -1%, meaning the RTX 4070 SUPER trails it by 1% in average score.

Within the RTX 4070 SUPER’s own benchmark suite, the strongest results appear in synthetic and compute workloads. It scores 29995 in Passmark G3D, 17108 in Passmark GPU Compute, 205624 in Geekbench Vulkan, and 172795 in Geekbench OpenCL. In 3DMark Steel Nomad DX12, it scores 4627. Passmark legacy tests show 344 in DirectX 9, 273 in DirectX 11, 167 in DirectX 10, and 110 in DirectX 12, along with 1184 in G2D.

The Arc G3 Extreme’s percentile rank of 50 places it at the median of all GPUs in the database, but with an average benchmark score of 0 and no recorded tests, this percentile appears to reflect its positional ranking rather than measured performance. The RTX 4070 SUPER’s 83rd percentile is based on an average score of 43223 across ten recorded benchmarks.

The Verdict

The data shows that the NVIDIA GeForce RTX 4070 SUPER is the superior performer by every measurable metric. Its 7168 shading units, 224 texture mapping units, 80 render output units, 56 RT cores, and 224 tensor cores provide a 4.7x shading unit advantage, a 4.6x FP32 advantage, and a 4.6x pixel rate advantage over the Intel Arc G3 Extreme. Its 504.2 GB/s of dedicated GDDR6X bandwidth is a fixed, known quantity, whereas the Intel part’s System Dependent memory bandwidth cannot be guaranteed at any level.

The RTX 4070 SUPER’s recorded benchmarks confirm its position in the 83rd percentile of all GPUs with an average score of 43223, placing it within 1% of the RTX 4090 Mobile and essentially tied with the Quadro M6000 variants. The Intel Arc G3 Extreme, with an 80 W TDP, no power connectors, and an IGP form factor, is built for a different class of device entirely. Its 50th percentile rank with no recorded benchmark scores suggests it is a mid-tier integrated solution.

For users requiring a discrete GPU with 12 GB of VRAM, 35.48 TFLOPS of FP32 throughput, and a 267 mm dual-slot card with a 16-pin power connector and 550 W suggested PSU, the RTX 4070 SUPER is the clear choice based on recorded data. For systems that cannot accommodate a discrete card, the Arc G3 Extreme’s 80 W TDP, integrated bus interface, and portable-device-dependent display outputs indicate a mobile-first design. The RTX 4070 SUPER is end-of-life with a successor in the GeForce 50 series, while the Arc G3 Extreme remains in active production.

The decision is not about which GPU is better in absolute terms, but which fits the intended platform. The RTX 4070 SUPER’s 35.48 TFLOPS and 504.2 GB/s bandwidth serve desktop workloads that demand sustained throughput. The Arc G3 Extreme’s 7.680 TFLOPS and system-shared memory serve devices where 220 W of power and a PCIe slot are unavailable. The recorded data supports only one conclusion for performance: the RTX 4070 SUPER dominates, but the Arc G3 Extreme exists in a segment where that dominance is irrelevant.
